AMD has claimed leadership in the entry-level server space with the new AMD EPYC 4004 series. Intel needs to go do a re-do as AMD enters the market with EPYC processors that are based on an AMD Ryzen platform.

Really wish they would have included extra PCI-E lanes. Something like a 4/8c chip with 48 or 64 PCI-E v5 lanes. There's not much out there for those of us wanting that kind of connectivity other than Ebay EPYC x002/x003 chips/boards.

@geofrancis2001 Месяц назад

@LordApophis100 Месяц назад

That would mean another socket because AM5 is too small for that amount of lanes. For lower lane count theres also Bergamo and Threadripper.

@draskuul Месяц назад

More PCIe lanes, more RAM slots and M.2-22110 support (though that's on the MB and not the CPU). It really seems like full ECC is all the Ryzen-Epycs really add.

@Ojref1 Месяц назад

You mean, the effort of creating a motherboard where the manufacturer installs a pcie switch or another PCH to get more lanes? Ha ha ha, oh no. They aren't going to do that except in very special cases, very proprietary cases. Both AMD and Intel dictate implementation rules. They've been slowly taking away PCIe lanes and slots on consumer products, and they sequester remaining lanes in m.2 or add excessive 1GB NICs to tie them up. They want you buying the server or workstation platforms. Asrock Rack motherboards that have desktop processor sockets are practically no better than their desktop counterparts for this reason.

@wewillrockyou1986 Месяц назад

Agreed, a big weakness of AM5 (and AM4) in general is the very limited total number of PCIe lanes, there is nothing you'd put in a low end server that needs PCIe 5.0, the vast majority of these budget use cases would much rather have 3+ times as many 3.0 lanes.

@geofrancis2001 Месяц назад

@@wewillrockyou1986 the problem with that is it will just push the motherboard cost up to the same as a threadripper or epyc, since you still have to route all those lanes, that means a lot of layers making it very expensive. they have low core count epyc for those use cases.

At work, I built 2 servers for CAD/EDA work. These things can be pretty compute intensive, and at the same time take limited advantage of multi core. Since large cache size, and high single core performance are the most helpful, I have one ryzen 7950x3d system with 128G and another EPYC 9384X system with >500G, for whenever something needs a lot of ram. People really prefer the Ryzen system whenever possible, because it is just so noticeably quicker. If there was any way of getting more ram on the Ryzen, that's all I would buy for that kind of workload.

You don't need anything like that to run a nas. Slap a N100 and call it a day. AM4/AM5 is horrible at idle, unless it's a mobile based monolithic chip. E.g. 3000g. Plus the advertised 65w am4/am5 are actually 88w electrically.

I wonder if it's possible to bifurcate the PCIe lanes. I have a couple of AI workloads that are (somehow) not as PCIe bandwidth bottlenecked as you would expect, so I could possibly get away with x4 connections on a huge number of GPUs, and this server would fit really well with my power consumption issues.

@OpinionatedFrench Месяц назад

What a sweet sweet machine. This will give the opportunity for large bare metal server rental companies to offer massive performance for cheap !! Plus it would be excellent for a remote GPU server for remote gaming or AI (usually faster cores win over core count ) Exciting times Thanks Patrick from STH 😊

Honestly other than guaranteed ECC UDIMM support, i'm not very interested in 4004 The platform is great, that is an easy way to get guaranteed support for people who dont want to research what consumer boards work for their use case.(edit, i'll probably pick up a board for my 7950x to replace my x670E PG lightning) But for me to care about 4004 processors it needs to be more than just consumer cores in an enterprise motherboard. I'll give some examples of what i'd like to see from Epyc 4004 or 4005 There are ~370 extra pins over AM4 sure some of those are going to be for power, but most likely are for 'future expansion' so maybe these 4004 could have a different IO die option, and enterprise motherboards could add a 3rd channel of RAM These are being called Epyc, why not Zen4C for up to 32 cores. If they dont want to open pandora's box like Intel did with the first gen i7 LGA 1366 and subsequent people upset by the 2700k not having 3 channel, then maybe add another 8-16 PCIe lanes from those 370 pins. honestly i was surprised the 7940HX/8940HX/8700G dont support tripple channel, the iGPU is starved for bandwidth even at 8000 in 1:1 the 8700G seems starved, with notable improvements just going from DOCP 8000 to an OC of 8400

@Superkuh2 Месяц назад

Such a shame they didn't give them more than 2 channels for RAM. A "low end"-"high end" high memory bandwidth solution is needed by many.

@ServeTheHomeVideo Месяц назад

I think Siena fills that void

@TrueThanny Месяц назад

@@ServeTheHomeVideo Sienna only has Zen 4c cores, which clock a _lot_ lower. Having some standard Zen 4 cores on SP6 would have filled the gap between 9004 and 4004, as 8004 just doesn't do it.

@_-Karl-_ Месяц назад

So, can you compare the Epyc 4464P to the Ryzen 9 7900? 4 more PCIe lanes and explicit ECC support, is that it?

@fujinshu Месяц назад

More like, you don't need a chipset for the Epic 4004 CPUs (compared to Ryzen, where 4 of the 28 lanes are reserved for the chipset), so all the PCIe lanes can be utilised however you want.

@_-Karl-_ Месяц назад

@@fujinshu I was trying to look at that on TechPowerup. The 4004 chips must still need a chipset link for SATA, LAN, Wifi, etc., right? As I understand it all there is are BIOS changes to get the current AM5 motherboard chipsets (B650, X670, etc) to work with the 4004s?

@mikebruzzone9570 Месяц назад

Advantek and Lenovo predate Ryzen ECC commercial work group and industrial server and workstation so around since Vermeer. Ryzen parts were being used by all the typical Asia Pacific ODMs for small office work group and for some time I get extension of 'Pro' as 'into' commercial / industrial . . . The fact is there are a ton of Raphael at run end and yes Epyc 4000 made sense. Raptor E channel available gained + 258% in the last month so this should be an easy virtual desktop and workstation group server race for AMD to win relying on a desktop part. mb

This is a great move. I was not able to tell what the RAM limit is. Anyone know that? The Ryzen 7000 platforms out there now are pretty limited for RAM. For my homelab, a 4 core or 6 cores CPU is fine for running like 20 VMs, but my issue is available RAM for that many VMs. Even being miserly with it, the Ryzen platform was limited. I hope that in addition to this move, they also do a refresh of the EPYC 3000 series. Basically, I want Zen 4 or Zen 5 cores, but lower power like the EPYC 3000 series. 25~65W range but with 4-16 cores. I believe there is a market for that.

@allanwind295 15 дней назад

Would the 16 core Epyc 4665P draw 170w if given a 12 core 4464P (65w) workload on Linux? The mixed core thing that Intel has been doing says otherwise but I thought the fundamental result was race to finish so you can power down the core.

@ServeTheHomeVideo 15 дней назад

No it would not. Two things though. As you go the V/F curve, things get less efficient so usually same core lower wattage does well. Second, there are still a lot of 120W/U racks out there so a 65W TDP CPU fits but a 170W can incur overages.
